y 2` Claims.

This inventionl relates to awnings of the Venetianblind type, and lin particular an awning formedv with a pair of stringers held in spaced relation by rods extended through the ends thereof and provided with slat receiving recesses in the outer edges, and a plurality of slats, triangular shaped in cross section removably mounted in the'recesses of the stringers.

The purpose of this invention is to provide an improved type of awning that may be shipped before assembly and that .is' formed with V-shapedslats which diiuse reflected light without reducing the heat intercepting characteristics thereof. l

Various types of awningshave been provided using metal strips of different designs but metal awnings of this type are heavy and when shipped assembled are diiiicult to handle. Numerous attempts have also been made to ventilate awnings of this type to permit air to escape through the awning without reducing the emciency of the awning. With these thoughts in lmind this invention contemplates an awning in which triangular shaped slats are removably mounted in recesses in stringers and the stringers are held together by rods with the stringers clamped against shoulders of the rods by lock nuts.

The object of this invention is, therefore, to

provide means for forming an awning with continuous Ventilating openings therethrough and in which slats providing the body of the awnings areal-nicely positioned in recesses in stringers or supporting elements.

Another object of the invention is to provide an awning of the collapsible type in which the parts are shipped in a compact unit and readily assembled without permanently attaching the parts-a further object of the invention is to provide an awning of the collapsible type and having permanent Ventilating openings therethrough which is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a pair of parallel bars with recesses in the edges of one of the sides thereof, with slats freely positioned in the recesses and with the stringers clamped in spaced relation by rods extended therethrough.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

Figure 1 is a longitudinal section through the awning taken on line I-I of Figure 2.

Figure 2 is a front elevational view showing the awning.

vwith slats Iil carried by stringers II and l2 with- ,Figure vis a detail illustrating one of the slats -Of the awning. ,u

Figure 4 is a detail showing the shape of the recesses in the edges of the; stringers. y

YFigure Sis a detailshowingone end of one of the slats in combination with a Stringer, said detail being a section taken on line 5-5 of Figure, 1 with part oi the sla-t broken away.

Figure 6 is a cross section through V,oneendof the awning taken on line 6 6 of Figure l showing one of the rods for clamping the stringers in spaced relation.

Referring now to the drawings wherein like reference. characters denote corresponding parts the improvedawning of tlL's invention is formed the stringers secured in spaced rel-ation by rods I3 and I4 in which the stringere are clamped against shoulders I5 at the ends of the rods I3 and I4 by lock nuts I6 on threaded studs I'I at the ends of the rods.

The ends of the stringere II and yI2 are provided with openings I8 in which the studs II are positioned and the outer edges of the stringere are provided with recesses I9 having converging sides 2U and 2 I, as shown in Figure 4. The inner walls of the recesses, as indicated by the numeral I9 slope inwardly, the upper end walls 20 slope downwardly and the lower walls 2I slope upwardly whereby with the V-shaped slats l0 pressed together yas they are inserted in the recesses the sides thereof spring outwardly with the upper web 22 bearing against the wall 20 of the recess and the lower wall or base, as indicated by the numeral ID bearing against the short wall 2I of the recess. The upper web or section 22 of the slat is! provided with notches 23 and 24 that receive the edges of the stringere I I and I2, as illustrated in Figure 1. To facilitate gripping of the stringers by the slats the upper walls or webs 22 of the slats are arcuate, the outer part thereof being formed on a radius as shown in the drawing, The lower section to which the numeral ID refers is illustrated as being flat.

It will also be understood that the slats may be of any shape or design and may be formed of corrugated instead of flat material and the width of the sections may also be varied to change the positions of the slats in the stringers.

The awning as illustrated and described may be mounted with the usual awning supporting elements or may be supported by any suitable means.

With the parts arranged in this manner the V'shaped slats, the stringers II and I2 and the through the surface of the awning and with the slats formed in the V-shaped light passes through the awning whereas the direct sun rays which carry heat are intercepted unless the sun is in such a position that the light rays therefrom are substantially parallel to the Webs 22 of the slats. These openings are comparatively small and the sun would remain in this position a relatively short period of time.

It will be understood that modifications may be made in thev design and arrangement of the parts without departing from the spirit of the y invention.

What is claimedis:

l, Ina collapsible awning, vthe combination which comprises a pair of 'supporting stringers with 'spaced recesses -in the outer edges and having openings therethrough spaced from the ends thereof,rods having threaded studs on the ends positionedbetween the stringers with the studs extended 'throughthe openings'. inthe stringere, lock nuts threaded on the studs of therodsefor clamping the stringers against the shouldersof therods, andfslats V-shaped in cross section 'having upper and lower'webs With out-v 'l wai-diy extended vertexes positioned in the recesses of the stringere with the webs engaging the upper and lower ends of the recesses, the upper webs of said slats being arcuate and having notches in the edges thereof to receive corresponding edges of the stringers.

2. An awning having a plurality of spaced stringers with spaced recesses in the outer edges, the inner-,walls of said recesses sloping upwardly and inwardly, the upper end'wallssloping downwardly 'and inwardly' 'from the edges of the stringers and the lower end walls of the recesses sloping upwardly and inwardly, means retaining 'the stringers in spaced relation, and slats V- shaped in cross section having upper and lower A webs withoutwardly extended vertexes posi- 'tioned in the recesses of the stringers with the webs engaging the upper and lower ends of the recesses, the upper webs of said slats being arcuate and having notches in the edges thereoi` to receive corresponding edges of the stringers.
